History of the Microscope Foldable
Anyway, I've had my students create various forms of timelines to go with this lesson over the years, but I think this one might be my favorite.
Each student needs 7 index cards and one piece of construction paper.
The index cards get folded in half. On the 'cover' goes the date and the scientist. Inside the card goes the scientist's contribution.
The folded cards get glued to the construction paper.
1300s Italian monks... ...begin grinding lenses.
1590 Janssen... ...compound microscope
1665 Hooke... ...looked at cork; coined the term "cells"
1665 Leeuwenhoek... ...discovered "animolecules" (which were acutally bacteria)
1838 Schleiden... ...plants are made of cells
1839 Schwann... ...animals are made of cells
1855 Virchow... ...all living cells come only from other living cells
